BEST Lubricants For Door Locks

9 Best Lubricants For Door Locks In 2022 (Tested)

A door lock is made up of many parts that need to work together smoothly and quietly in order to function properly. If they don’t move freely, they can become difficult to operate, which will frustrate both you and the person entering or leaving your home.

Door lock lubricant prevents rust from building up on the surface of your locks, which often happens as a result of moisture getting inside and forming rust deposits over time. This could cause problems with opening/closing or locking/unlocking the door (if there are no other issues). Here are some of the most important considerations when choosing a lubricant for door locks:

Temperature: You want to make sure that whatever lubricant you use is safe for use in high-temperature environments. High temperatures can cause an oil-based lubricant to degrade and lose its effectiveness.

Water resistance: A key feature of any good lubricant is its ability to remain effective even after exposure to water. This is important because many people store their bicycles outside and they may experience rain or snow.

Viscosity: Lubricants vary widely in terms of viscosity – some are thin while others are thick; this is important because it affects how long each product takes to penetrate into an area and start working effectively. The thicker the lubricant, the longer it will take before it penetrates into an area e.g., if there is a problem with sticking locks or chains then using a thicker product might help solve this problem faster than using a thinner product would do.

Straw Construction: A straw construction is one such feature that makes it easy to apply the lubricant onto the latch. You can simply insert the straw into the keyhole and then use it to spray lubricant on all sides of the keyhole. This will ensure that all parts of the keyhole are covered with lubricant, including its interior parts as well as its exterior sections.

What to Look for When Buying Lubricant for Door Locks

There are many types of lubricants available in the market today. However, some are better than others. If you want to find the best lubricant for door locks, then you need to consider certain features before you make your purchase.

Features to Look for When Buying Lubricant for Door Locks

1. Waterproof

The best lubricant for door locks should be waterproof. This means that even if it rains heavily or if there is heavy snowfall, your car will still be safe from all types of weather conditions because of this type of lubricant.

2. Non-Toxic

 The lubricant should not be toxic at all as this can cause side effects such as poisoning or even death when used by children who play with them unknowingly or by pets who lick them up as food sources which is common in many homes today where there are pet dogs and cats running around freely without supervision all day long. Therefore, you need to make sure that your chosen door lock lube is non-toxic and safe for everyone including children who might find their way into it accidentally while playing around indoors or outdoors.

3. Corrosion Protection

If you are using a lubricant on your car door locks, it should offer corrosion protection to prevent rusting of the lock and its components. This is especially true for vehicles that are parked outside in the elements for long periods of time.

4. Ease of Application

Lubricants can be applied manually or with special tools depending on the type of lock being treated and its location. For example, if you need to apply grease to a lock that is installed beneath a car seat, you will need an applicator tool to do so effectively. Similarly, if you are applying grease to an inside door handle, it may require some elbow grease because it is not as easy to access as other parts of your vehicle’s interior such as undercarriage parts or even exterior surfaces like doors and hoods which are typically easier to reach due to accessibility issues.


We have listed a detailed buying guides for how to choose the best lubricant for your door locks. Next you can choose whatever suits your door lock and circumstances.

Hope this article was a help in your buying quest!
